Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3

Here are some answers
<u>Remember if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)</u>
<u>if leg b is unknown, then. b = √(c² - a²)</u>
<u>for hypotenuse c missing, the formula is. c = √(a² + b²)</u>
Have a wonderful day!

Answer:

Final Answer: 
Answer:
The answer would be 26
Step-by-step explanation: (Broken down into 2 parts)
-PART ONE- solving (12-7) x (8-5) -7
(12-7) x (8-5) -7 (do whats in parentheses first)
(5)x (3) -7 (multiply 5x3)
15-7 (subtract)
ANSWER- 8
-PART TWO- solving (16-4) + (10 - 12 divided by 3)
(16-4) + (10 - 12 divided by 3) (do what is in parentheses)
12 + 10-4 (add)
22-4 (subtract)
ANSWER- 18
Now combine the two answers 18+8 and you get 26
Therefore, 26 is the final answer.
Hope this helps!!
